I was like that for many many years (maybe 20?) then suddenly I never had problems with it. What I did back then was going in for a hand shake then I knew what was right. And the more I did it the less obvious I had to do the shake. I don’t know if this is why I don’t need to do it anymore but now days I am amazed by it instead every time because of how bad I was at it for so long.

I used to. Here is how I resolved it. Left starts with ‘L’. I 'L’ike ‘L’ a lot more than ‘R’. So, I started liking left more. When someone says left, I think, “Oh, the side that I like.” If they say right, then I think, “Oh, the side I like less.”

index finger and thumb on your left hand looks like an ‘L’. that’s the only way i can tell. someone taught me that in karate class as a kid and it’s saved my ass almost every day since.

Yes and my mind has a block between east and west

East and West for me.

I have to look at my hands to get it right. Palms down and thumbs out at right angles and the left hand looks like an L.

I got L and R tattooed on my (correct) thumbs to use as quick reference. They’re incredibly useful.
